Stressed out trees helping charities restore valuable aspen forests
Briefly

The aspen is one of the UK's scarcest but most valuable trees. To produce tiny, delicate seeds, 104 specimens are deliberately made to suffer.
Being stressed helps these aspen flower and produce the short-lived seeds that rewilding charities and foresters need to restore the aspen forests.
We treat them with lots of love for most of the year, but we can see in the wild that they respond to stress by flowering.
The British aspen's idiosyncrasies have perplexed the forestry community; it has a very narrow window of fertility each spring.
